4. CHAIN (ref. Dwg. MHP0102). Examine each of
the links for bending, cracks in weld areas or
shoulders, transverse nicks and gouges, weld
splatter, corrosion pits, striation (minute parallel
lines) and chain wear, including bearing surfaces
between chain links. Check lubrication and
lubricate if necessary. See 'Load Chain' under
"LUBRICATION."
(Dwg. MHP0102)
CAUTION
• The full extent of chain wear cannot be determined
by visual inspection. At any indication of chain
wear inspect chain and load sheave in accordance
with instructions in "Periodic Inspection."
• A worn load chain may cause damage to the load
sheave. Inspect the load sheave and replace if
damaged or worn.

5. LOAD CHAIN REEVING. Make sure welds on
standing links are away from load sheave. Re-
install chain if necessary. Check that the last link of
the load chain is securely connected. Make sure
chain is not capsized, twisted or kinked. Adjust as
required.
6. HAND LEVER. Check for cracks, bending and
other damage. Replace if necessary.
Periodic Inspection
Frequency of periodic inspection primarily depends on
the severity of usage:
NORMAL
yearly semiannually
Disassembly may be required for HEAVY or SEVERE
usage. Keep accumulative written records of periodic
inspections to provide a basis for continuing evaluation.
Inspect all items in "Frequent Inspection." Also inspect
the following:
1. FASTENERS. Check rivets, capscrews, nuts, cotter
pins and other fasteners on hooks, hoist body and
chain bucket, if used. Replace if missing and
tighten or secure if loose.
2. ALL COMPONENTS. Inspect for wear, damage,
distortion, deformation and cleanliness. If external
evidence indicates the need for additional
inspection return the hoist to your nearest
Ingersoll-Rand service repair center.
3. HOOKS. Inspect hooks for cracks. Use magnetic
particle or dye penetrant to check for cracks.
Inspect hook retaining parts. Tighten or repair, if
necessary. Refer to applicable specifications for
additional hook inspection information.
4. CHAIN SHEAVES. Check for damage or
excessive wear. If damage or wear is noted, return
the hoist to your nearest Ingersoll-Rand service
repair center.
